Interface Summary

Buildable
GroovyInterceptable	Marker interface used to notify that all methods should be intercepted through the invokeMethod mechanism of GroovyObject.
GroovyObject	The interface implemented by all Groovy objects which is handy for using Groovy objects when in the Java world
GroovyResourceLoader	Allows frameworks that integrate with Groovy to determine how Groovy files are resolved.
Interceptor	Implementers of this interface can be registered in the ProxyMetaClass for notifications about method calls for objects managed by the ProxyMetaClass.
Range	Represents the interface of a Range implementation which includes the from and to values
Writable	Represents an object which is capable of writing itself to a text stream in a more efficient format than just creating a toString() representation of itself.

Class Summary

BenchmarkInterceptor	Interceptor that registers the timestamp of each method call before and after invocation.
Binding	Represents the variable bindings of a script which can be altered from outside the script object or created outside of a script and passed into it.
Closure	Represents any closure object in Groovy.
DelegatingMetaClass
EmptyRange	Constructing Ranges like 0..<0
GroovyClassLoader	A ClassLoader which can load Groovy classes.
GroovyClassLoader.ClassCollector
GroovyClassLoader.InnerLoader
GroovyCodeSource	CodeSource wrapper class that allows specific security policies to be associated with a class compiled from groovy source.
GroovyObjectSupport	A useful base class for Java objects wishing to be Groovy objects
GroovyShell	Represents a groovy shell capable of running arbitrary groovy scripts
GString	Represents a String which contains embedded values such as "hello there ${user} how are you?" which can be evaluated lazily.
IntRange	Represents a list of Integer objects from a specified int up to and including a given and to.
MetaArrayLengthProperty	Represents a property on a bean which may have a getter and/or a setter
MetaBeanProperty	Represents a property on a bean which may have a getter and/or a setter
MetaClass	Base class for meta class implementations.
MetaClassImpl	Allows methods to be dynamically added to existing classes at runtime
MetaClassRegistry	A registery of MetaClass instances which caches introspection & reflection information and allows methods to be dynamically added to existing classes at runtime
MetaExpandoProperty	Represents a property in an Expando object
MetaFieldProperty	Represents a property on a bean which may have a getter and/or a setter
MetaMethod	Represents a Method on a Java object a little like Method except without using reflection to invoke the method
MetaProperty	Represents a property on a bean which may have a getter and/or a setter
NonEmptySequence	Represents a sequence of objects which represents one or many instances of of objects of a given type.
ObjectRange	Represents an inclusive list of objects from a value to a value using comparators
ParameterArray	Distinguish a parameter array from Object[].
PropertyValue
ProxyMetaClass	As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs.
Reference	Represents a reference to a value
Script	This object represents a Groovy script
Sequence	Represents a sequence of objects which represents zero or many instances of of objects of a given type.
SpreadMap	Represents a spreadable map which extends java.util.HashMap.
TracingInterceptor
Tuple	Represents a list of Integer objects from a specified int up to but not including a given and to.

Exception Summary

BitwiseNegateEvaluatingException
ClosureException	An exception thrown by a closure invocation
DeprecationException	Use this exception to mark a method implementation as being deprecated.
GroovyRuntimeException	An exception thrown by the interpreter
IllegalPropertyAccessException	An exception occurred if a dynamic property dispatch fails with a field not accessible.
IncorrectClosureArgumentsException	An exception occurred when invoking a Closure with the wrong number and/or types of arguments
MissingClassException	An exception occurred if a dynamic method dispatch fails with an unknown class.
MissingFieldException	An exception occurred if a dynamic field dispatch fails with an unknown field.
MissingMethodException	An exception occurred if a dynamic method dispatch fails with an unknown method.
MissingPropertyException	An exception occurred if a dynamic property dispatch fails with an unknown property.
ReadOnlyPropertyException	This exception is thrown if an attempt is made to set a read only property
SpreadListEvaluatingException
SpreadMapEvaluatingException
StringWriterIOException	An IO exception occurred trying to append to a StringWriter which should never happen.
